Disclosed is a drilling and/or striking hammer that includes a lubricating device having a lubricant reservoir and a volume of lubricant contained therein. The lubricating device conveys lubricant to at least one a transmission system within the hammer's housing, a percussion system, and/or a tool holder at a variable dosing or flow rate. The dosing or flow rate varies as a function of tool stress which can include use intensity and/or temperature. A flexible tube extends between the reservoir and the lubricated component(s). At lease part of the flexible tube vibrates with the lubricated components during use and modifies a viscosity of the lubricant therein, based on tool use intensity. A pressure generating device can pressurize the lubricant, helping convey the lubricant to a targeted area for lubricating movable parts.
